Effect of Shenfu injection on intestinal and lung flora in patients with sepsis⁃induced acute respiratory distress syndrome
injection(SF) on intestinal and lung flora in patients with sepsis⁃induced acute respiratory distress syndrome (ARDS).
Methods
2
From January to December 2022
twenty⁃two patients with sepsis⁃induced ARDS were enrolled at Renmin Hospital of Wuhan University. The patients were randomly divided into the conventional treatment group (control group) and the
Shenfu
injection treatment group (SF group). Bronchoalveolar lavage fluid (BALF) and fecal samples were collected from both groups. 16S rRNA and non⁃targeted metabolomics technologies were used to analyze the changes in microbial flora diversity and metabolites in the intestine and lungs before and after SF intervention
and to identify differential metabolites and metabolic pathways.
Results
2
(1) The BALF microbial Alpha diversity of the SF group was significantly improved as compared with that of the control group
and the Shannon index became larger (
P
<
0.05)
indicating that the richness of microbial species increased; there was no significant difference in fecal Shannon index and Beta diversity between the two groups. 29.97% of BALF microbial species originat
ed from feces
and
Bacteroidetes
which is common in feces
appeared in BALF. (2) LC⁃MS/MS showed that the tryptophan metabolism pathway in feces and BALF changed significantly after SF treatment (
P
<
0.05). Fecal KEGG enrichment analysis found that the expression of metabolite tryptophan and 5⁃hydroxyindoleacetate were both down⁃regulated (
P
<
0.05).
Conclusion
2
Shenfu
Injection has a tendency to enrich the diversity of BALF and fecal flora in patients with sepsis⁃induced ARDS
and participates in the tryptophan metabolic pathway
which provides a certain reference and basis for subsequent in⁃depth research on the mechanism of
Shenfu
Injection in the gut⁃lung axis of ARDS.
